The Steelers’ depth at running back may be significantly tested in Sunday’s game against the Falcons.
Harris is dealing with an oblique issue suffered in Monday’s victory over the Colts. He left that game in the first half and didn’t return.
Snell played well on Monday, taking 12 carries for 62 yards with a touchdown. It was the first time he’d carried the ball this season.
Pittsburgh also has Jaylen Warren on the 53-man roster plus Anthony McFarland and Master Teague on the practice squad at running back.
Receiver Miles Boykin (oblique) and Warren (hamstring) were both full.
Defensive tackle Cameron Hayward received a rest day.
